* The returned time-stamp token is a signed data that contains the digest value, the identity of the TSA, and

|
* the time of stamping. This proves that the given data existed before the time of stamping.

* NOTE: the term time-stamp token used does NOT refer to the TSA's response to a requesting client, but the
